[embodiment]
Hereinafter, by reference implementation example, comparative example and test case the present invention is described in detail.For those skilled in the art It is readily apparent that these are only illustrative example of the invention, and more specifically to explain the present invention, and it is of the invention Range is not limited by these embodiments, comparative example and test case.
The preparation of [embodiment 1 and comparative example 1 and 2] W/O/W multiple emulsion compositons
W/O/W multiple emulsion compositons are prepared according to composition (unit: wt%) shown in the following table 1.W/O is prepared respectively Then W/O emulsion compositions are mixed and are emulsified with O/W emulsion compositions, to make by emulsion compositions and O/W emulsion compositions Standby W/O/W multiple emulsion compositons.In the present embodiment and comparative example, the dosage of surfactant, which is less than, to be typically formed surely The amount of the surfactant of customization agent, and test and carried out under conditions of accelerating to stability reduction.
[table 1]
The preparation of [embodiment 2 and comparative example 3 to 5] W/O/W multiple emulsion compositons
W/O/W multiple emulsion compositons are prepared according to composition (unit: wt%) shown in the following table 2.W/O is prepared respectively Then W/O emulsion compositions are mixed and are emulsified with O/W emulsion compositions, to make by emulsion compositions and O/W emulsion compositions Standby W/O/W multiple emulsion compositons.In the present embodiment and comparative example, the dosage of surfactant, which is less than, to be typically formed surely The amount of the surfactant of customization agent, and test and carried out under conditions of stability reduces accelerated.
[table 2]
The preparation of [embodiment 3 and comparative example 6 to 8] O/W/O multiple emulsion compositons
O/W/O multiple emulsion compositons are prepared according to composition (unit: wt%) shown in the following table 3.O/W is prepared respectively Then O/W emulsion compositions are mixed and are emulsified with W/O emulsion compositions, to make by emulsion compositions and W/O emulsion compositions Standby O/W/O multiple emulsion compositons.In the present embodiment and comparative example, the dosage of surfactant, which is less than, to be typically formed surely The amount of the surfactant of customization agent, and test and carried out under conditions of stability reduces accelerated.
[table 3]
The appearance stability of [test example 1] evaluation composition
The composition of embodiment and comparative example is kept for one week at 25 DEG C, and evaluates the stability of composition.By one Zhou Hou is listed in table 4 and Fig. 4 according to the result that formulation aesthetics evaluate stability.
[table 4]
It distinguishes Stability
Embodiment 1 O (good)
Embodiment 2 O (good)
Embodiment 3 O (good)
Comparative example 1 X (inversion of phases)
Comparative example 2 X (inversion of phases)
Comparative example 3 X (inversion of phases)
Comparative example 4 X (inversion of phases)
Comparative example 5 X (inversion of phases)
Comparative example 6 X (inversion of phases)
Comparative example 7 X (inversion of phases)
Comparative example 8 X (inversion of phases)
It can be seen that all compositions in embodiment from the result of Fig. 4 and table 4 and all maintain good appearance, but compare Inversion of phases all has occurred compared with all compositions in example.Even if can be seen that the composition of especially embodiment 1 small by 24 When after still keep stable emulsion state, but in oily phase not comprising ionic material comparative example 1 preparation excessively complete 12 Inversion of phases has occurred before hour, the preparation of the comparative example 2 in water phase not comprising ionic material is sent out before 24 hours excessively complete Inversion of phases is given birth to, and these preparations cannot be stably kept.
[test example 2] observes a variety of emulsion particles
Multiple emulsion particle by observing the composition of above-described embodiment and comparative example evaluates the stability of composition.
The emulsion particle of the composition of embodiment 1, comparative example 1 and comparative example 2 is observed immediately after preparation, the cream The microphoto of liquid particle is shown in Fig. 5 to 7.As can be seen that the composition of embodiment 1 is in stable multiple milk liquid State, wherein emulsion particle is distributed in other emulsion particles, but the composition of comparative example 1 and 2 does not form multiple emulsion state simultaneously And the coalescence of oil phase particulate has occurred.
After preparation immediately to the emulsion particle of the composition of embodiment 2 carry out observation and keep at 25 DEG C after a week into Row observation, the microphoto of the emulsion particle are shown in Fig. 8 and 9.As can be seen that existing immediately after preparation and even just By after a week, multiple emulsion particle is kept in stable conditionly.On the other hand, as can be seen that i.e. from the comparative example of Figure 10 3 Make to be the agglomeration phenomena of multiple emulsion particle just also to have occurred immediately immediately after preparation, therefore do not stabilize.
